I like this design. But I've changed some stuff around.
Hyperdrive <> Middle Reactor.
Right Crew <> Top Reactor
The now TopCrew <> Right Storage Bin

Then extend the engine cluster down by one and fill with Corridor. And place walkways up/down on the sides.

This protects the reactors at the core bulk of the ship. The Hyperdrive efficiency raises a bit and crew movement around the ship becomes really speedy.

Thankyou for uploading it for me to use as a base idea :)
